2 Claims.

This invention relates to improvements in' sink llxtures, and has to dowith combination fixtures in which valves for hot and cold water are in.

corporated to control the flow of either one or a mixture of both from acommon exit. `Fixtures of this kind commonly employ a swing spoutldisposed between the two valves through which the water is delivered. Itis also known to provide in addition to the swing spout a hoseconnection with a spraynozzle on the extremity thereof through whichwater may be delivered if desired and to provide a diverter valve bymeans of which the operator may cause water to iiow alternatively eitherto the spout or to the spray nozzle. The present invention is concernedwith an improved means for accomplishing the latter purpose.

One of the objects of the invention is the provision -of a screw valvecooperating with either of two opposed valve seats, both of which areimmovably positioned in the valve body.

Another object of the invention is the provision in valve apparatus ofthe character stated of a diverter valve which shall be'positive andcertain in action and which shall have two positions into either one ofwhich it may be setwithout regard to the position of the swing spout.

Other objects and features vof novelty will appear as I proceed with thedescription of that embodiment of the invention'which, for the purposes'of the present application, I have illustrated in the accompanyingdrawing, in which:

Fig. 1 is a plan view of a sink fixture embodying the invention. v

v, Fig. 2 is a vertical section taken-substantially on the line 21-2 ofFig. l.

Figs. 3 and 4 are horizontal detail sectional views taken substantiallyon the lines 3-3 and 4--4 respectively of Fig. 2.

In the drawing, I0 represents the ledge of a metal sink directly behindthe sink cavity. A Suitable openings II, I2 4and I3 are provided in thisledge for the reception of the upstanding parts of a valve body locatedotherwise beneath the ledge. These upstanding parts comprise threadedsleeves I4 at each end of the-fixture,- n'only of which is illustrated,and a central s1, eve I5. The fixture is clamped to the ledge II) bymeans of nuts I6 threaded on the two sleeves I4 and working throughwashers I1 to grip the ledge against --radial flanges I8 on the iixture`below the ledge.

Two valve stems I9 and 20 with handles 2I .and 22 at their upper endsare provided for turning on or off the hot and cold water respectively.These valves may be identical in construction. and

4I) arranged as illustrated at theI left side of Fig. 2, may comprise athreaded collar 23 turning in av correspondingly threaded wall 24 andhaving a valve piece 25 arranged to engage a removable and replaceablevalve seat member 26. In order tol present a Ysmooth exterior thesecontrol valves comprise metal escutcheons 21 and 28 which are preferablyplated and polished and are held in position by clamping nuts 29 and 30.

Hot and cold water, represented by the'arrows A and B, may enter thevalve body when the control valves at thepends of the iixture are openand will then flow inwardly toward and into the central sleeve memberI5. Positioned centrally within the latter member there is a tubularcasting 3| with a valve seat 32 at its upper end. This casting isthreadably mounted in the valve body at 33 and has a downwardlyprojecting nipple 34 for receiving a flexible rubber hose 35 which isclamped to the nipple by a hollow nut 36. While not herein illustrated,it is to be understood that the hose 35 may extend upwardly through. anopening in the ledge III and may carry on its opposite extremity a spraynozzle for rinsing dishes, fruit, and the like.

The valve body above the sleeve member I has an upwardly continuingportion 31 roughly cylindrical in shape which is provided with'a@assur-D I UUT 1 4 1941 downwardly facing valve seat 38 that is opposedj to and spaced from valve seat 32. The body member 31 is preferablymounted in the sleeve member I5 byl a threaded joint as shown and ishollow to provide a path for water to ow upwardly from the valve seat38. Intermediate itsL length this body member has a spider or bridge 33in which are formed a series of perforations in a circle surrounding acentral threaded opening in which is mounted a threaded vportion 4I of avalve stem 42. This valve stem has a reduced lower end upon which ismounted Aa metal washer 43 with peripheral flanges extending bothupwardly and downwardly. Gaskets 44 and 45 are positioned in thecavities formed by these flanges," the upper gasket being adapted toengage valve seat 38 and the lower gasket being adapted to engage valveseat 32. The lower extremity of the stem 42 is threaded and has aattened side indicated at 46, Fig. 3, in order to receive a D-washer 41.A nut 48 threaded onto the stern works through D-washer 41 to clamp thewasher 43 with its gaskets 44 and 45 against the shoulder atvthe upperend of the reduced portion of the stem, the D-washer acting as a lock toprevent accidental loosening of the mounting for the gaskets.vObviously. when the stem is threaded downwardly gasket 45 engages seat32 and provides a passage for water upwardly, while threading the stemupwardly unseats gasket 45 and causes gasket 44 to engage seat 88,thereby providing a passage for water downwardly through casting 3|. Onthis central part of the xture an escutcheon 49 similar to theescutcheons 21 and 28 is employed.

50 is a swing spout which at its rear end has a downwardly projectinghollow trunnion 5| that extends into body member 3 1 and has a bore oflarger diameter than the external diameter of the stem 42. Suitablemeans are provided to rotatably support the trunnion 5| within the bodymember 31 which, in the illustrated embodiment, comprises a split springring 52 that is set within an annular groove formed in the trunnion, thering 52 resting upon an annular shoulder 53 of the body member. Abovethe ring there is a suitable packing 54 which is heldin place by a glandnut 55. A short tubular extension 56 is provided on the upper side ofthe spout 50 in alignment with the trunnion 5|, through which the stem42 protrudes with clearance. This ex tension is threaded externally toreceive a gland nut 51 covering packing 58.

A hand wheel 59, or other form of hand grip, is secured to the upper endof stem 42 for convenience in turning the latter. The threads`4| arerelatively coarse and prefer'eably of such pitch that a movement of thestem is sumcient to actuate the diverter valve from one operativeposition to the other. In order that the operator may know how the valveis set at any given time the handle 59 may be marked to provide that in-`formation, as for example by the letters H, meaning hose, and S,meaning spout. When the H is forward, as in Fig. 1, the Valve is set tocause ow of water throughl the hose. When the handle 59 is turned fromthat position clockwise through 180 however the letter S will be infront, which will indicate that the valve is set to cause flow of waterthrough the spout.

It will be observed that both of the valve seats 32 and 38 are portionsof the valve body and are therefore fixed in position at all times.Also, the operation of the valve by screw action provides positiveengagement of the valve with either one of its seats, eliminating anyleakage of water from the outlet not then in use and serving to hold thestem against rotation when the spout 50 is swung from one position tothe other.

Having thus described my invention, I claim:

1. In a combination xture, a central upright valve body having thereinopposed spaced valve seats through which water may flow upwardly ordownwardly, a swing spout mountedin the upper end of s aid valve body, avalve stem extending through said spout concentric with the axisv aroundwhich the spout turns and threadably mounted in the valve body belowsaid spout, a double valve piece on the stem for engagement with one orthe other of said seats alternately, and a handle at the upper end ofsaid stem above said spout operative through a predetermined angleregardless of the angular position of the spout for moving the valvefrom one operative position to the other.

2. In a combination xture, a yhorizontal conduit, a valve at each end ofsaid conduit, a sleeve member extending upwardly from the middle of saidconduit, a tubular casting extending upwardly from said conduit intosaid sleeve member and having a projecting lower end carrying a nipplefor attachment to a flexible hose, a valve seat at the top of saidcasting, a body member removably secured to said sleeve member andextending upwardly therefrom, a downwardly facing seat in said bodymember, a diverter valve stem in said body member carrying a doublevalve piece adapted to cooperate alternatively with either of saidseats, a swing spout oscillatably mounted in the upper end of said bodymember concentrically with said stem, and a handle for the stem abovesaid swing spout whereby the diverter valve mechanism is locatedentirely above the said horizontal conduit for accessibility inservicing.
